Shipping integration - open to bidding

hi, we are stuck with shipping in Magento. We dont now how to create shipping labels and extract tracking number from fedex. We have fedex Account and keys. We have A/c details entered in Magento "Shipping Method". < But when we try to ship order and we choose Fedex. < we dont get any tracking number there. In fact we have to enter it manually. So, whats the point of using Fedex details or API? We dont know to integrate our store with fedex. This all we want to do: 1. Generate shipping label which includes all required details (like customer details, product name, Invoice value, weight, dimension etc) 2. Generation of lables with pickup request. 3. Return shipping label. 4. Email - Notification to customer of dispatch and delivery In short we dont know how to integrate shipping. Please let us know if you can help us out in this.
